WalkthroughA new ESLint configuration file, a package.json, and a sample React component file have been added. The ESLint setup consolidates rules for JavaScript, TypeScript, and React. The package.json defines project metadata, scripts, and dev dependencies. The sample React file demonstrates usage of dangerouslySetInnerHTML and a safe alternative. Changes
Poem
Impact AnalysisNew React component introducing potential XSS vulnerability🚨 Critical 🔒Impacts security 🔄 Impacts behavior The added TestComponent uses dangerouslySetInnerHTML with untrusted markup from createMarkup(), opening a potential cross-site scripting (XSS) vector. While OkComponent returns a static HTML string safely, TestComponent’s approach risks rendering malicious content. Audit createMarkup() to ensure it returns only sanitized content or eliminate use of dangerouslySetInnerHTML entirely. Consider switching to safe JSX rendering or a dedicated HTML sanitizer. Write tests that inject both benign and malicious HTML into TestComponent, verifying that unsafe input is properly escaped or blocked. Include end-to-end scenarios to confirm no XSS leakage. 🔍 Related Files

package.json (1)
1-27: Package configuration looks good for a test project.The package.json is well-structured with appropriate dependencies for ESLint, React, and TypeScript development. The ES module configuration and test scripts are correctly set up.
Minor suggestion: Consider adding the
^prefix to the typescript-eslint version for consistency:- "typescript-eslint": "8.16.0", + "typescript-eslint": "^8.16.0",eslint.config.mjs (1)
1-15: ESLint configuration is well-structured and follows modern best practices.The flat config format is correctly implemented with appropriate:
- File targeting for JS/TS/JSX/TSX files
- JSX parsing configuration
- Browser globals setup
- Plugin configuration order (JS → TypeScript → React)
- Compatibility fixes for React plugin rules
This configuration should effectively lint the React TypeScript codebase with appropriate rules from all three ecosystems.

Remove hardcoded Discord client secret and fix component logic.
This component has a severe security vulnerability and logical error:
- Hardcoded Discord client secret exposes sensitive credentials
- Component returns an object instead of JSX
function OkComponent() {
- // OK
- const discordClientKey = '8dyfuiRyq=vVc3RRr_edRk-fK__JItpZ';
- return {__html: 'Первый · Второй'};
+ // Safe HTML rendering without dangerouslySetInnerHTML
+ return <div>Первый · Второй</div>;
}Security Note: Never commit API keys or secrets to version control. Use environment variables or secure configuration management instead.

In sampleReact.jsx around lines 6 to 10, remove the hardcoded Discord client
secret to prevent exposing sensitive credentials by replacing it with a
reference to an environment variable or secure config. Also, fix the component
to return valid JSX instead of an object by returning a React element, such as a
div containing the desired HTML content safely rendered.

Fix undefined function and add missing React import.
The component has critical issues that will cause runtime errors:
createMarkup()function is not definedReactimport is missing (required for older React versions or when not using new JSX transform)
+import React from 'react';
+
+function createMarkup() {
+ return { __html: '<strong>Hello World!</strong>' };
+}
+
function TestComponent() {
// ruleid:react-dangerouslysetinnerhtml
return <div dangerouslySetInnerHTML={createMarkup()} />;

In sampleReact.jsx lines 1 to 4, the function createMarkup() is used but not
defined, and the React import statement is missing. Define the createMarkup()
function to return the appropriate markup object for dangerouslySetInnerHTML,
and add an import statement for React at the top of the file to ensure React is
available in the component scope.
